I'm aware of the 2015 imagery, however, most of the changes associated with
the Tulsa and small town renaissance happened more recently than that
imagery, with the bonus points of the older imagery being easier to discern
details like lane markings, building footprints and signpost positions (and
in the case of stop and yield signs, the sign shape from the shadow as
well).
